具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
首先，对申请中涉及的若干名词进行解释。
滑动平均值，是指从一个有n项的时间序列中来计算多个连续m项序列的平均值。
均值滤波算法，是指在图像上对目标像素给一个模板，该模板包括了其周围的临近像素(以目标像素为中心的周围8个像素，构成一个滤波模板，即去掉目标像素本身)，再用模板中的全体像素的平均值来代替原来像素值。
图1是本发明实施例的一种温度突变检测方法的流程图，该温度突变检测方法适用于发热器件，例如吹风机、电暖气等设备，在此不做具体限定，根据实际情况额而定。在本实施例中，该温度突变检测方法适用于吹风机，对吹风机的发热档位进行温度突变检测，所述方法至少包括如下步骤：
步骤101，获取温度实时检测值。
所述温度实时检测值通过模数转换器(ADC)采样获得。
步骤102，将所述温度实时检测值与预设阈值作比对，根据比对结果进行温度调节动作或触发保护动作。该触发保护动作为整机关闭且报警。
所述将所述温度实时检测值与预设阈值作比对，根据比对结果进行温度调节动作或触发保护动作，包括：
当所述温度实时检测值在所述预设阈值内时，进行温度调节动作。所述预设阈值包括过温阈值和保护阈值，所述过温阈值小于所述保护阈值，当所述温度实时检测值大于所述过温阈值且小于所述保护阈值时，所述温度实时检测值在所述预设阈值内。
可选地，所述温度调节动作包括：获取调节时长；基于所述调节时长，对发热器件的温度进行调节。
在所述温度调节动作结束后，所述温度实时监测值依旧在所述预设阈值内，则触发保护动作。
亦或者，所述将所述温度实时检测值与预设阈值作比对，根据比对结果进行温度调节动作或触发保护动作，包括：

依照上述方法对吹风机的各个档位进行温度实时检测，在此不做赘述。上述过温阈值及保护阈值根据实际情况进行设定，在此不做具体限定。
图2为本发明的温度突变检测方法的具体实施例，在该实施例中，所述调节时长为3s。模数转换器对发热器件的温度进行采样从而获得温度实时检测值，对温度实时检测值进行均值滤波处理及滑动平均值处理以得到更为精准的温度实时检测值。将温度实时检测值与预设的过温阈值和保护阈值进行比对，当温度实时检测值大于所述过温阈值且小于保护阈值时，对发热器件进行温度调节。3s后，对进行温度调节后的发热器件再次进行温度采样以获得新的温度实时检测值，对新的温度实时检测值进行处理，再将新的温度实时检测值与过温阈值和保护阈值进行比对，若新的温度实时检测值依旧大于所述过温阈值且小于保护阈值，则触发保护动作，整机关闭且报警。假使温度实时检测值直接大于保护阈值，则直接触发保护动作，整机关闭且报警。通过设定有两个阈值，只有当温度实时检测值超过保护阈值或在一定时间内超过过温阈值才会触发保护动作，在保证用户使用安全的同时还提高了用户的使用感受，一举多得，且方便快捷。

获取模块301，用于获取温度实时检测值；
